Thanks for your request.
For first you have to check:
1. DropBox login is correct.
2. DropBox password is correct.
3. Folder path correct. For test – leave this field empty.
Better register new DropBox account. Especially for photos sharing on your blog.
Also give me please your gmail or write me : portablecomponentsforall@gmail.com.
